If I want to rotate a vertex(all vertices of an object ofc), can I use glRotate?

You can use glRotate to build a matrix if you wish. It’s not the only way but you can do it.
To rotate all your certifies you multiply each one by the matrix and the result is a rotated vertex.

I think he is asking if he can use glTranslate, glRotate, glScale, glFrustum, glOrtho on the other matrices like projection or texture or color matrix.

Yes you can.
However, this is old OpenGL and you should move into shaders already since it is 2011. The matrices no longer exist and neither does glTranslate.
